The Convention Centre of Milano MiCo is located inside the existing Pavilion 6 of the Fiera Milano City. With its 18,000 seats subdivided into 70 modular rooms, an auditorium with 1,500 seats, and a plenary chamber with 5,000 seats, it is the biggest convention centre in Europe. For the redefinition of the internal spaces, in relation to their adjustment to the convention activities, the following criteria have been respected: to achieve a continuity with the Convention Centre of Pavilion 17; to maintain the building bodies of the existing, realizing the transformations of the internal sections through light and modular structures; to respond to the present functional exigencies of the convention and exhibition activities.
